Bosch original Replacement Diesel Engine Fuel Pump Injector 1440579 for Scania 4-series Engine DC11.03 DC11.04 DC11.08 DC11.09 DC12.02 DC16.02 original new injector

Purpose-built for the Scania D12 engine platform, this Bosch original unit fuel injector (OE 1440579) is an electronically controlled pump-nozzle assembly for heavy-duty diesel service. Unlike common-rail injectors, it integrates the high-pressure pumping element, injection nozzle and solenoid valve into one cylinder-specific unit mounted directly in the cylinder head, eliminating any external high-pressure line and enabling precise, cylinder-individual fuel metering.

The integrated architecture generates very high injection pressure exactly where fuel is needed, supporting clean combustion, stable torque and dependable starting across the DC11, DC12 and DC16 engine range. Electronic actuation allows the engine management system to control injection timing and quantity with high accuracy, helping fleets sustain fuel efficiency and emissions performance over long service intervals. Supplied as an original Bosch component in new condition, the injector offers OE-matched calibration, fit and durability for demanding commercial operation.

Cross references include Scania 0574393 (also written 574393), Bosch 0414701019, 0414701027 and 0414701082, plus Bosch eXchange numbers 0986441015 and 0986441115. Documented applications cover Scania 114, 124, 164 and G, P, R, T series trucks and buses—including the G340, P340, P380, R340, R380, T340 and T380—powered by DC11.03, DC11.04, DC11.08, DC11.09, DC12.02 and DC16.02 engines. Because unit injectors are calibration-specific, buyers should confirm compatibility using the engine code, engine serial number, chassis number and original injector markings before shipment.
